The correct functioning of the safety system must be checked periodically (monthly or accord-
ing to overruling regulations). The sensor and wiring connections must also be checked for
mechanical damage.
Proceed as follows if the function is not assured based on the wiring in the circuit diagram and
both yellow or red LEDs light up at the same time:
1. Press reset button (min. 1 sec.)
2. Check all sensors to determine if activated or damaged
3. Check sensor resistance on terminals 1/2 and 3/4 (8.2 kOhm)
4. Repeat commissioning
There is a unit fault if both red LEDs continue to light up afterwards.
Return the unit for
checking.
If only one yellow or red LED lights up Return the unit for checking.

• The maximum length of the sensor with cable must not exceed 50 metres
• Maximum surface area 5 m

• If multiple sensors are used, they have to be connected in series
• The last sensor equipped with resistor 8.2 kOhm
• If only one sensor input is used channel 2 must be jumpered (provided resistance
8,2 kOhm ±1%), otherwise a fault signal is generated
